Kafka AdminClient DEFAULT_API_TIMEOUT_MS_CONFIG property not working as expected.

[shruti pandey]

Hi,

I have previously send this query.

In my java application for kafkaProducer i created Admin and used this to
list topics.

 Admin admin1 = Admin.create(properties).
ListTopicsResult listTopicResult = admin1.listTopics();

When producer was not able to connect to broker, thread get stucks at
listTopic step.

To avoid this i have added DEFAULT_API_TIMEOUT_MS_CONFIG property and have
set to 2000ms. so after 2s if producer is not able to connect to broker
timeout should happen.
properties.put(AdminClientConfig.DEFAULT_API_TIMEOUT_MS_CONFIG,2000). But
this does not work as expected. even DEFAULT_API_TIMEOUT_MS_CONFIG with
value 2000ms as property timeout didn't happen and thread was struck.

Is there any other way to achieve timeout or do we need to configure it in
any other way? Also is using AdminClient instead of Admin can have any
impact.


Also our Admin creation was successful. Even though we have kept
request.timeout.ms=100 there was no error or exception thrown. We used this
admin to list out topics present in broker and it was successful.

One thing I would like to point out is that we have created Admin not
AdminClient. Will this be having any impact. Let us know about it.

This is how we used it



try (Admin admin1 = Admin.create(properties)) {

                                           ListTopicsResult listTopicResult
= admin1.listTopics();

                                           KafkaFuture<Set<String>>
kafkaFuture = listTopicResult.names();



Thanks in advance

Thanks
